A proposition so strange, it just might work...Brother Roommate by Wendi Lynn

Blurb:
Logan's marriage crashed and burned after the birth of his twin daughters. An absent mother left the girls disrespectful and looking for the wrong kind of attention at only thirteen years old. He knows something has to change and when he meets the wife of a friend and sees the well-behaved children she has successfully raised, Logan wonders if he can find another woman like her.
Ashton and Derrick are happily married with four kids. Things were good, and they bought a large house which required an even larger mortgage. When Ashton loses her job and suddenly their cushy lifestyle is shattered, they struggle to make ends meet.
As if things couldn't get worse for Logan who battles for custody of his girls, his apartment floods leaving him nowhere to go and a judge that needs to see him living a stable life. That's when Derrick suggests he move in and with it a proposition so strange, it just might work.

But will they be able to do it, or will they successfully tear the families apart?
